Newbie Directory & Search Engines

Hi all

I would like to know which directories and search engines you submit your sites to. I know there are thousands of directories out there most of them from what I understand are a waste of time.

What are your top 20 must submit to links?

Thank you!

Everyone prefer getting listed in high PR directory DMOZ, but its very difficult now-a-days. Submit your site to some other high PR directories. I prefer PR4+ directories.
